He Rangahau Hōhonu mō te Hononga i waenga i te Hanganga me te Mahi o te Koiri Rino Galvalume

I roto i ngā mara pēnei i ngā pakitara ārai hanga, ngā whare taputapu, me ngā whāriki photovoltaic, kei te whakakapi haere ngā koiri maitai galvalume i ngā koiri maitai galvalume tuku iho hei whiringa matua nā te mea he rua ngā painga o te ātete ki te waikura me te whai hua o te utu. Ahakoa ko te Utu Koiri Maitai Galvalume, he mea nui hei whakaaroaro i roto i te hokohoko hangarau, ko teASTM A792 GalvalumeI roto i ngā paerewa whakaputa, kua mārama te tautuhi i ngā whakatakotoranga matua, ā, ko ngā rerekētanga o te mahi matua i ahu mai i te mana whakahaere tika o te hanganga. I tēnei rā, ka tīmata tātou me te tātari hanganga hei wetewete i ngā mea ngaro o te mahi o ngā koiri maitai galvalume (tae atu ki te Galvalume Roll, Steel Coil Galvalume, me ētahi atu).
I. Te Tātaritanga o te Hanganga Matua o te Koiri Rino Galvalume
Ko te mahi a ngā koiri maitai galvalume ka whakatauhia e te "rauemi turanga" me te "paninga". Ka pā tika ngā ōwehenga wāhanga rerekē ki ngā āhuatanga e tika ana mō te hua whakamutunga. Hei tauira, ko te hoahoa hanganga o te Galvalume Steel Coil Az150, e hiahia ana kia nui te ātete ki te waikura, he rerekē rawa atu i te hoahoa o te Galvalume Coil noa.
1. Te Hanganga o te Paninga: Te "Ōwehenga Koura" o te Konumohe, te Konutea, me te Hiraka

Ehara te paninga konumohe-konute i te konganuku kotahi, engari he pūnaha koranu o te konumohe (55%), te konutea (43.5%), me te silicon (1.5%). Ko tēnei ōwehenga te otinga tino pai kua whakamanahia mā te mahi roa:
* Konumohe (Al): Ko te "uho ātete-waikura" o te paninga. Ka hangaia e te konumohe he kiriata waikura Al₂O₃ matotoru ki runga i te mata o te koiri maitai, ka taea te ātete ki te waikura mai i ngā taiao kino pēnei i te ua waikawa me te rehu tote. Koinei te take matua he 3-5 ngā wā teitei ake te ātete o ngā koiri maitai kua pania ki te konumohe-konutea i ngā koiri maitai piauau noa;
* Konutea (Zn): He "tiaki patunga tapu." Ina rakurakuhia te paninga, ka pai ake te tauhohenga o te konutea ki te hāora hei ārai i te waikura o te maitai turanga. I taua wā anō, ka taea hoki e te noho o te konutea te whakapai ake i te ngāwari o te paninga, kia māmā ake ai te piko me te tā mo te Galvalume Roll;
* Hiraka (Si): Ka whakatau i te raruraru o te "piripiri paninga". Ka taea e te hikareti te aukati i te tauhohenga i waenga i te konumohe me te rino hei hanga i ngā matū whakarewa Fe-Al pakarukaru me te mārō, ka whakaiti i te tūponotanga o te kiriuhi paninga. He mea nui te pānga pumau o te hikareti mō te Galvalume Steel Coil Az150 matotoru ake (AZ150 e tohu ana i te 150g o te taumaha paninga mō ia mita tapawha).
2. Te Hanganga o te Papa: Te "Taurangi Taketake" o te Rino Waro-Iti

Ko te papa ongā koiri maitai galvalumehe rino waro-iti te nuinga (he nui te waro ≤0.12%), he iti noa te konupūmā (0.3-0.6%) me te whākōkī (≤0.045%): Waro (C): Mā te nui rawa o te waro ka tino mārō te papa, ka ngawari te pakaru i te wā e tukatukahia ana; mā te iti rawa o te ihirangi ka whakaiti i te kaha o te koiri rino. Nō reira, me tino whakahaere te nui o te waro o te rino waro-iti i roto i te "awhe taurite kaha me te kaha tukatuka"; Manganēhi (Mn): Mā te iti o te konupūmā ka taea te whakapai ake i te kaha hua o te papa me te kore e pā nui ki te ngāwari, kia pai ai mō ngā tono kawe kawenga (pēnei i te koiri rino galvalume mō ngā whāriki photovoltaic); Whākōkī (P): Mā te Whākōkī ka whakanui ake i te pakarukaru o te rino, nō reira me tino whakawhāiti te nui o te whākōkī i roto i te papa, koinei hoki tētahi o ngā tohu kua tohua mārama i roto i te paerewa ASTM A792 Galvalume.
II. Te Hononga i waenga i te Hanganga me ngā Āhuatanga Matua o te Mahi Mā te mārama ki te hanganga ka mārama tātou he aha ētahiNgā Koiri Galvalumehe pai mō te hanga o waho, ko ētahi he pai mō ngā whakapuru taputapu—ko te mea nui kei roto i ngā rerekētanga mahi e puta mai ana i ngā whakarerekētanga hanganga.

1. Ātete ki te Waikura: Ko te Ihirangi Konumohe e Whakatau ana i te "Taumata Tiaki" Ko te ātete ki te waikura te whakataetae matua ongā rōra galvalume, ā, he tino tika tōna whanaungatanga ki te hanganga: Ina piki ake te ihirangi konumohe o te paninga mai i te 50% ki te 55%, ka tino pai ake te mātotoru o te kiriata waikura Al₂O₃. I roto i ngā taiao rehu tote i te taha moana, ka taea te whakaroa i te wā waikura o te koiri maitai mai i te 10 tau ki te neke atu i te 20 tau. Mena kei raro iho i te 1% te ihirangi silicon, ka heke te piri i waenga i te paninga me te papa, ka ngawari te paninga ki te pupuhi i roto i ngā whakamātautau rehu tote; mena kei runga ake i te 2%, ka nui ake te pakarukaru o te paninga, ka whakaiti i te ātete ki te waikura. Koinei anō te take he kaha ake te ātete waikura o te Galvalume Steel Coil AZ150 i te AZ100 (100g paninga ia mita tapawha) – ehara i te mea he matotoru ake te paninga, engari he pai ake te ōwehenga konumohe-konutea-silicon ki ngā whakaritenga tiaki teitei.
2. Ngā Āhuatanga Ā-ringa: Ko te Hanganga o te Papa te mea nui rawa atu i te "Kaha me te Āheitanga ki te Tukatuka"
Kaha: Mō ia pikinga 0.1% o te ihirangi konupūmā o te papa, ka taea te piki ake o te kaha whakaputa o te koiri maitai mā te 5-8 MPa. Nō reira, mō te Koiri Maitai Galvalume e whakamahia ana i roto i ngā mahi amo kawenga, ka whakahaeretia te ihirangi konupūmā ki te 0.5-0.6%.
Te Āheitanga ki te Tukatuka: Mō ngā tono e hiahia ana ki te tānga uaua, pērā i ngā anga taputapu, ka tīpakohia ngā papa he ≤0.1% te ihirangi waro, ko te ihirangi silicon o te paninga ka whakaitihia ki te 1.5% hei ārai i te pakaru o te paninga i te wā e tāngahia ana. 3. Te Ātete ki te Pāmahana Teitei: Te Painga o te Konumohe ki te "Pūmautanga ki te Pāmahana Teitei"
He teitei ake te ira rewa o te konumohe (660℃) i te konutea (419℃), nō reira, he pai ake te ātete pāmahana teitei o ngā koiri maitai konutea konumohe i te ātete o ngā koiri maitai piauau:
I ngā taiao i raro iho i te 200℃ (pērā i ngā arai oumu), he pumau te mahi paninga;
Ahakoa i raro i ngā pāmahana teitei mō te wā poto o te 300℃, ka taea e te kiriata Al₂O₃ te ārai i te waikura o ngā paninga, koinei te tino take e pai ai te Galvalume Roll mō ngā auahi me ngā whakakikorua paipa pāmahana teitei.

III. Te Hononga i waenganui i te Hanganga, te Mahi, me te Utu o te Koiri Rino Galvalume

He maha ngā tāngata e whakaaro ana i te wā e hoko ana: He aha te rerekētanga utu o te Galvalume Coil o ngā whakaritenga ōrite ka eke ki te 100-200 RMB/tana? Ko te tikanga, ko te rerekētanga utu e whakaata ana i te utu o ngā wāhanga: Te utu paninga: Ko te utu mākete o te konumohe e 2-3 ngā wā i te konutea. Nō reira, ko te teitei ake o te ihirangi konumohe i roto i te paninga (hei tauira, AZ150 ki te AZ90), ko te teitei ake o te utu, ā, ko te teitei ake o te Utu o te Galvalume Steel Coil. Te utu rauemi turanga: Ko te teitei ake o te ihirangi manganese me te iti iho o te ihirangi phosphorus i roto i te maitai waro-iti, ko te teitei ake o te utu whakarewa, ā, ko te teitei ake o te utu Galvalume Steel Coil e rite ana. Te utu paerewa: Ko ngā hua e rite ana ki te paerewa ASTM A792 Galvalume he kaha ake te whakahaere i te manawanui wāhanga (hei tauira, te rerekētanga ihirangi konumohe ≤ ±1%), he tere para teitei ake i te wā whakaputa, ā, he utu 5-8% teitei ake i ngā hua kore-paerewa. IV. Tauira Whakamahinga Whaihua: Te Hiranga o te Kōwhiringa Hanganga

I whakaritea e tētahi kaupapa hanga takutai ngā momo porowhita maitai galvalume e rua: Porowhita Galvalume noa (50% konumohe, 1% silicon): I puta te waikura ā-rohe i muri i te 3 tau o te whakamahinga; Porowhita Maitai Galvalume Az150 (55% konumohe, 1.5% silicon), e rite ana ki te ASTM A792: Kāore he waikura nui i muri i te 5 tau o te whakamahinga, ā, kāore he rerekētanga i te wā o te pānga o te awhiowhio (ngā āhuatanga miihini pai rawa atu). I te mutunga, i whiriwhiria e te kaupapa te mea whakamutunga. Ahakoa he 150 RMB/tana te utu tuatahi o te Porowhita Maitai Galvalume, i roa ake te ora ratonga neke atu i te 10 tau, ā, i iti ake te utu whānui mō te wā roa.

Whakamutunga: Ko te hoahoa hanganga o ngā koiri maitai galvalume he tukanga "kia tino ōrite ki ngā whakaritenga": ka whiriwhiria te AZ150 (konumohe teitei, silicon teitei) mō te ātete waikura teitei; ka whiriwhiria ngā papa silicon iti, waro iti mō te tukatuka uaua; ā, ka whiriwhiria ngā hua paerewa ASTM A792 mō ngā kaupapa kaweake. I te whanaketanga o ngā ahumahi photovoltaic me te pūngao hou ā muri ake nei, ko te arotau hanganga (pēnei i te tāpiri i ngā rahinga iti o ngā huānga whenua onge hei whakapai ake i te ātete waikura) ka noho hei huarahi whanaketanga nui mō ngā koiri maitai konutea konumohe, ka whakawhānui ake i ō rātou rohe tono.
